egg dirt

The black, burned, residue left behind on one's metal skillet following the cooking of an egg (scrambled, sunnyside, over-easy, etc.). This residue is usually combined with whatever substance that may be left behind from prior use.

Deriving from an individual, usually found sleeping in a parking lot, who frequently eats hard boiled eggs. One of which has been peeled and has fallen onto the ground and rolled through a soft, fine dirt; and despite his or her best efforts cannot be cleaned. Obviously the individual eats the egg and occasionally feels guilty of his or her actions, occasionally.
